About this tool
Press Start recording and your browser asks what to share: the whole screen, a window or a browser tab. The tool records it with the browser's built-in MediaRecorder and, when you stop, gives you a WebM video to preview and download as recording.webm. It does not use ffmpeg and nothing is uploaded; the video stays in your browser's memory until you save it. It records the screen only, not your webcam or microphone. The checkbox reads Capture tab/system audio (if the browser offers it); it asks the browser for the shared tab or system sound, which depends on the browser and what you choose to share. It needs a desktop browser that supports screen capture and WebM recording, such as Chrome, Edge or Firefox.
How to use it
- Leave Capture tab/system audio checked or uncheck it.
- Press Start recording and pick a screen, window or tab in the browser prompt.
- Press Stop, or end sharing from the browser bar, when you are done.
- Preview the video and press Download.
Common problems
- It says screen capture is not supported
- Use a recent desktop version of Chrome, Edge or Firefox. Most mobile browsers cannot capture the screen.
- The recording has no sound
- Sharing a Chrome tab or a screen with 'share audio' ticked is needed for tab or system sound. The tool never records your microphone.
- Recording fails to start on Safari
- The tool requests WebM, which Safari may not support. Try Chrome, Edge or Firefox.
- I closed the page and lost the video
- Recordings are held in memory only. Download before leaving the page.
